doesn't car polish have wax in it? tooth paste works well on deep scrachs best stuff to use is ring remover get this at a hardware shop for taking white cup marks out of polished tables this is a very fine abrsive in a liqued that removes wax/crap and the abrsive sands the surface so the mark is removed and leaves the table top very shiny also stuff called g3 rubbing compound used for restoring carbody colour is very good you can get this from any motor factor
hopes this helps
